Heat Thunderstorms in Austria: Weekly Forecast

On Tuesday, thundery rain showers will already occur in the west from the early morning hours, and conditions there will remain muggy-warm and unsettled throughout the day. While it is expected to remain dry in the lowlands on Tuesday, early morning temperatures will range between ten and 20 degrees, with daily highs reaching 25 to 33 degrees. In the eastern half, the sun will mostly still shine in the morning alongside high cloud fields, but as the day progresses, cloud fields and cumulus clouds will continue to spread, and in general, the likelihood of showers and thunderstorms will increase significantly over the hilly and mountainous regions. The wind will be light to moderate and will tend to shift to westerly during the day.

Tuesday: West Unsettled First

On Wednesday, low pressure in high layers will bring an increasing likelihood of thunderstorms and showers across all of Austria. Early morning temperatures will be 13 to 21 degrees, with daily highs already reaching 28 to 33 degrees. The wind will pick up repeatedly from different directions. Heat thunderstorms with temperatures above 30 degrees Celsius will move across the country.

Wednesday: Thunderstorms Throughout Austria

On Thursday, the influence of low pressure in high layers over Austria will decrease somewhat. During the course of the day, the initially still fairly widespread showers and thunderstorms will become less frequent, and the sun will break through again – with a freshening north wind, especially in eastern Austria.

Thursday and Friday: Calming in the East

On Friday, there will be only minor differences in surface pressure at high atmospheric levels. From the west, air pressure will drop again in high layers, increasing the likelihood of thunderstorms during the day from Vorarlberg to the Salzkammergut region. Further east, sunshine will predominate, with showers and thunderstorms being rare. In the far east, conditions will even be cloudless during the day. There will be a light wind, with early morning temperatures between eleven and 21 degrees and daily highs of up to 34 degrees in the east.

The weather outlook illustrates the typical July alternation between high-summer heat and vigorous thunderstorms. Those spending time outdoors should keep an eye on the daily updated forecast, as thunderstorms can vary significantly from place to place according to Geosphere Austria.
